I had my cruise control set exactly to the speed limit going down the highway (I rarely speed) and I got pulled over by a municipal cop in an unmarked police car. It took me a while to pull over because I didn't notice him until he pulled next to me. By the time the cop pulled me over he was livid. He kept trying to get me to admit I was speeding and I wouldn't do it. The discussion got more intense until he was yelling at me. I think he finally realized he screwed up and wrote me a warning.
